FP-60F-D/DV
Installation
Provide basket removal clearances and strainer installation provisions in accordance with the requirements given in
the Design Engineer Guide section above. Install the strainer with the flow arrow on the body pointing in the desired
flow direction.
The strainer should be installed such that the flushing valve Drain Flange is at the lowest point of the strainer, 3" to
12" strainers have the flushing valve port on the cover that can be rotated to be at the lowest point, this is to facilitate
efficient cleaning of the screen while flushing.
The strainer shall be installed on the pipeline upstream of the sprinklers, pressure control valve, deluge valve or any
other sensitive system device. Install a listed isolating valve upstream of the strainer. An adequate support shall be
provided to carry the system installation as well as the dynamic loads.
It is recommended to install a differential pressure gauge rooted to upstream and downstream of the FP-60F-D/DV
strainer, in order to show the degree of strainer blockage. The maximum allowable differential pressure across the
strainer is 7 psi or 0.5 bar at maximum system flow.
Placing In Service
Verify that all strainer cover bolts are well tightened, close the drain plug and/or drain valve, slowly open the supply-
isolating valve and check that there are no leakages. Observe the system pressure gauge: it should indicate that the
normal supply of water pressure is maintained.
Typical Installations
The BERMAD FP-60F-D/DV strainer is ideal to be installed
upstream of the BERMAD Pressure Control Valve, preventing
the fouling of valve sealing surfaces and keeping the
waterways clear from obstructions.
The BERMAD FP-60F-D/DV strainer should be installed
upstream of the Deluge, Foam system or Automatic Sprinkler
system, preventing debris particles from clogging the
nozzles and other sensitve devices.
